"Please... Don't leave me."
Eight-year-old Hayato Jokudera left his family and lived like a wild dog on the streets. One rainy night, he bumped into the kidnapped girl - Yu Watanabe, the only daughter of the SC chaebol. She was huddled in the corner of the alley, her blue hair stained with blood, like a baby bird soaked by the rain.
Yudera, who was supposed to leave indifferently, stopped because of the bleeding wound on her right eye.
——That night, he broke into the enemy camp and snatched her back from the kidnappers, but he also planted an obsession in her heart.
"You are my light."
Six years have passed, and the girl who was once rescued has become his "shadow". Watanabe Yu dragged his scarred body and stubbornly followed Gokudera's back. But he was always tired of this dependence——
"A drag." He sneered and shook off her outstretched hand.
"Trash." He sneered, watching her fall and then get up.
"Get out." He turned around, leaving her alone to tremble in the rain.
Until one day, Watanabe Yu fell in front of his door covered in blood, clutching the red-stained training record in her hand - it was proof that she was almost masochistic in order to become stronger.
"... Take me in." She cried and grabbed the corner of his clothes, "I will become - someone useful to you."
Yudera finally saw the determination in her eyes.
——It turns out that the sharpest blades are often forged from the broken hearts.
Intent: Shattered blades turn into light, obsession creates eternal blades
